Test-and-repair stations are licensed by the state to
provide Smog Check tests and repairs to most vehicles.
Under current law, test-and-repair stations are
prohibited from certifying repaired Gross Polluters or
vehicles that have been directed to Test-Only stations
for inspection. Only Test-Only stations and Gold Shield
stations are able to certify repaired Gross Polluters.

Decades ago, California became known as the nation's
"smog capital" because of the poor air quality in the
Los Angeles basin area. Los Angeles County sits in a
"bowl" topped by a layer of air that won't permit heavy
particles to break up in the atmosphere.

In the early 1960s, people began to worry about the bad
air outside. In 1963, California became the first state
to institute emission controls on new vehicles sold in
the state.

Since then, California has led the nation in concern for
the environment and controlling vehicle emissions. The
California Department of Motor Vehicles requires the
owners of most cars to adhere to strict emissions
regulations in order to register them.
